One more advice from crypto expert.
Only invest money that we can afford to lose if we want to invest for a long term. Because crypto investment is so agile our assets can be turned to 0 in short time and also can mulitplied in a short time also.
that's right, don't use the funds that we really need.
we must use other funds that are not needed in the near future, we must take into account all the needs that we use. so as not to panic sell when the price of a coin is in bad condition.
also make sure the coins we will buy have good potential in the future.as you say "crypto investment is so agile" anything can happen from giving us profits to making the value of our assets zero in just a short time. i hope the assets we hold never become zero.
